I would like to know if there is a way to add code to the check out page for conversion tracking purposes with google analytics and adwords.

Once I can place tracking code onto the checkout page I'll be able to track purchases as conversions and how the customer navigated the site before reaching the checkout page before the purchase and further more how the customer and other potential customers are getting to the site.
